To all whom it may concern:

Be it known that I, Cnannas R. SEYMOUR citizen of the United States, and resident of Rochester inthe county of Monroe; and State of llew York, have invented certain new and useful Improvements in Machines for A plying Box-Corner Stays, of which the following is a specification.

This invention relates to that class of machines adapted for applying stays or reinforcing strlps to the corner joints of boxes or other rece tacles made of paper-board or like material and in which are embodied stay strip applying means and stay strip feeding means; the said feeding means be ing operative to feed a continuousstay-strip from a supply roll to said applying means to be acted upon thereby'in usual and welllmown manner.

The present invention relates particularly to improvements in the stay-strip feedln mechanism of such class of machines, an has for its object the revision of a feeding mechanism that will e ca able of effective operation under all conditions of work and without liability of undue friction or wear on the working parts thereof. This object is attained by means of the novelfeaturesof construction and combinations of parts hereinafter described and claimed.

Referrin 'now to the accompanying drnwin s forming part of this specification,-- igure 1 is a side elevation, partly-in section 0 a machine embodying my'invention. l i 2 is a front elevation of the machine. lugs. 8 to Tinelusive, are enlar ed detail-views of different arts of the feeding! mechanism tobe hereina ter referred -to.;

Similar reference characters desi nate like parts in the several figures of the raw- ]ll is shown in said drawingsyxthe main, frame of-the machine is-formed by 8I1-lillt6{ gral casting embodyin a horizontal .bedplatel, a vertical stan ard 2. at" one end 0f said bed-plate, a horizontal arm 8 flii'the'llsr. per end of saidrstandard overlying the be -a plated, andia vertical web-"4 eonnecting atritsmar iii-with the said -bed-plate thei stander and overlyin arm}: Thisrfram' upon. which zthd severe 1 operative .parts; of;

the machine 'are' mounted, id supported at I the proper height upon a suitable sub-frame orsupport 5, aportion only of which is shown in the drawings.

The stay-a plying meansof this machine is substantia ly the same as that of other machines of the same class and includes two cooperating resser dies, one of which is normally stationary and the other reciprocator 'Il he stationary 'die, which is also termed an anvil, is indicated at 6. This die is in the form of an elongated'bar arran ed horizontally and sup orted in the stan ard 2 somewhat above t e bed-plate 1 with its front end extending beyond the face side of the standard to support the b xes or other work thereon. The said die or anvil 6 is fitted to slide longitudinally in its seat or bearing in the supportin frame so that its front end rtion may fie extended a greater or less istanoe from the face of the standard 2 aceordin to the depth of the box to be stayed. Said 1e or anvi may be secured in its adjusted position by an suitable means, the means ierein shown or such purpose comprising a clam -bar 7 .restin at one end on a riser 8 on the ed-plate an at its other end resting on the upper flattened portion of the rear end of the anvil and being adapted to be-heldinclamping en agement with said anvil by means of a c amp-screw 9. The other or reci rocatory die, indicated at 10, is located at t 6 front side of the standard 2 for cooperation with' the-upper face of the projectm .front' end of the lower die or anvil-6,1111 is suitablyattached to a vertically acting slide or plun r 11 which is operative in ides.12, 12, att 0 face side of the standarfi and-eonnected through the medium of asuitablyconstructed pitm'an 13 with an actuating part,-.here shown; as a crank-pin l4 ca'rrie at the front end of a driving shaft--15 mounted in theaifpper horizontal arm 3 of the su porting rams; said shaft being adap to be connected with, or disconnected'from a drivin pulley 16 through the -rnedium,;o fl a suitab e clutch; (not: shown) --for1,thefurpose of controllin theaa'ction of the-die.

' the continuous strip, andthcrcafter causes the die 10 also carriedthercby'to apply the severed sta to the box corner by cooperation-with-t to lower die, in usual and vvellknown manner. I willnow describe the construction and operation of the'said stafi fecding"mechanism. This feeding meoanism' comprises a reciprocatory strip-engaging devlce togethor with meansfor crating said device in a manner whereby it will be caused to engage and carry forward the strip in its forward feeding movement and then become released fromv the strip at the limit of its forward movement so as to move backwardly: without reducing any corresponding-movement of t e strip.. Said strip-engaging device itself is of substantially usual and well-known construction and comprises a plate 18 slidably connected with a stationary guide-plate 19 and having connected therewith two cooperating grippin jaws arranged to )ermit of the passage of-t e stay-strip there tween; one of said jaws, indicated at 20, being fixed with respect to theplate-IB and locatedin positionforenga ement with the stay-strip at the under-sh e thereof, and the other jaw, indicated at 21', being pivoted to the plate 18 and located in position for en 'agement. with tho'strip-at the'upperside thereof; Withthisconstruction of device,.the movable or pivoted jaw 21 should be caused to 006perate with the jaw 20 tot-engage andctrry forwardthe strip uponthe forward'movement of tho'device and'lto'roleasethe strip' atthelimitof thoforwardmovement of the device and maintain such release during-the returnmovement of the devicew Such operation of the-strip-engagii1 "devioe imeffectod'in the present casean .in accordance. with my invention by suitable means-operated: from the vertically acting-plungeri 11.- 0f the stri -applying means. The" said plunger-11 as connected therewith at its rear side a raclogear 23whicl1'1 meshes with a sector-gear 24- through an intermediate, sector-"car 25 to impart'an oscillating movement thereto, .the said sector-gears bothl ben ing mounted on bcaring-pins-or studs'pro jecting from aboss QG-omthe frame, stand.

Aswell'known by those familiar with the art, the length of stay fed between the dies 6-10 should'vary according to the depth of the box to be stayed, and this is arranged s for by the provision of meansfor regulating the length of the feed' stroke or movement ot the strip-engaging'devicet In the present case two sto s are provided for engagement with the fees lever-27 toregulate the extent. 8 of its movement and thereby that of the connected strip-engaging device; one of the stops, indicated at 32, hmitin the forward movement of thelever and tie other stop. indicated at 33; limiting the backward 9 movement of the lever. The stopis shown as-being formed at the upper end of a lever 34 which is pivoted to the web t of the supportin frame at. withits lower end having a s otand in connection 36 with 9 the rear-end," of the is or-anvil 6.

In view of the fact thatthe lunger 11 hasraisubstantiallyi fixed or predetermined length: of' stroke, while that of the stripengagin :device is adjustable, it \villi be-un- 1 derstoo that the: connections between-the said plungerand the stri rengaging device shoul'd'be suflicientlyyiel able-to permit of any difference" imthe: movements of said 'parts. For instance, the movement of the 1 gear'24 asiimparted thereto from the pluner 1i1.-is snfhcient to im art amaozimum ength of feedtstroke toitiestrip-engaging deviceebutinicase the stop 33'iis set to cause a shorter lengthiof feedstroke to said stlip- 1 engaging device; the feed: leverr 9-7 will i he enga'g'edl'by the stop 33 and:its movementbe limited thereby: prior to the limit ofn upwaird movementIofzthe-plungen To provide for thisland' permit of: the full. movement of 1 tltq'plu awithout b'rewleage'or o heridamageito t e connecting parts the connection between the sector 24 and the lever 27 is a flexible or yielding one and is providedas follows: The sector and-the :lever are respectively rovided with a shoulder 38 and an anti-fr ction roll 39 (the latter bein mounted on a pin 39 connected to the lever which said shoulderand-roll are yieldingly held in engagement with-each other by a coiled sprin 40 located on a sleeve or bushing on thc earing pin 28 with its opposite ends on aging ins 41 and'42 located respective y on t e said sector and. lever. With this construction and arrangement of parts, when the lever 27 comes in contact with the stop 33 rior to the completion of the up stroke of tie plunger, as referred to, the spring 40 will yield and permit of further movement of the connecting gears and said plunger without breakage or other dama e to the arts. On the down stroke of the p unger, t e movement of the gears will again bring the shoulder 38 of the sector 24 into engagement with the roll 39 of the lever 27 and cause a positive forward or feeding movement to said lever and the connecte stri -engagin device.

pen the orward or feeding movement of the lever 27 and connected strip-engaging device, the said lever is brought into enga ement with the forward etc 32 prior to t e limit of the down stroke 0 theplunger and connected parts. In view of this and in order to permit of the complete stroke of said plun er, a yieldable connection is also provided lietween the plunger and the rackgear 23 in a manner as follows: The said gear, which is slidably fitted within a way 44 in the plunger, is provided with a perforated ear 45 fitting over a vertical pin 46 in a cutaway 'ortion or recess of the plunger and yiel ingly held against the ower wall of said recess by a spring 47 interposed between said ear and tie upper wall of the recess, as clearly shown in Fig. 1. With this construction and arran ement of parts, when the feed lever 27 is imited in its forward movement by the stop 82, as indicated by dotted lines in Fig. 1, the continued downward stroke of the plunger, for the purpose of operatin the cutting and clampin devices, is ermitted by the yielding of t 1e spring 4 without undue strain. breakage or other damage-to the associated parts. Upon' the return upward stroke of the plunger, said (plunger positively engages the rack-gear an operates the several connccted parts to return them to position-for another feeding stroke, as before described.
